DETAILED DESCRIPTION

In the following detailed description, reference is made to theaccompanying drawings, which form a part hereof. In the drawings,similar symbols typically identify similar components, unless contextdictates otherwise. The illustrative embodiments described in thedetailed description, drawings, and claims are not meant to be limiting.Other embodiments may be utilized, and other changes may be made,without departing from the spirit or scope of the subject matterpresented here.

Referring generally to FIGS. 1 a and 1 c, a discharging device 103 and areceiving device 104 for obtaining an analyte from a body 101 aredescribed in accordance with various embodiments. The body 101 maygenerally include any biological entity having a protective skincovering, such as a mammalian entity (e.g. a human, a dog, a cat, oranother mammal), an avian entity (e.g. a bird of prey), as well as otherbiological entities having protective skin coverings. The dischargingdevice 103 collects at least one analyte from within the body 101. Thenthe discharging device 103 ejects the collected at least one analytefrom the body 101 through at least one dermal layer 102 of the body 101.In some embodiments, the at least one analyte may be collected and laterejected after being stored in receptacle 106. In alternativeembodiments, the at least one analyte may be collected and immediatelyejected without being stored in receptacle 106. Then the receivingdevice 104 receives the ejected at least one analyte that has beenejected from the body 101 through the at least one dermal layer 102.

The at least one analyte may be generally defined as any material withinthe body 101 that is obtained from the body 101. For example, thedischarging device may collect at least one of blood, a blood componentsuch as plasma or serum, cells, proteins, bacteria, cerebral fluid,cerebral spinal fluid, lymph, lymphocytes or other components of thelymphatic system, molecules, viruses, viral particles pathogens,parasites, malarial parasites, oligonucleotides, seminal fluid, semen, atherapeutic agent present in the body 101, or other materials from thebody 101 or at least a portion thereof.

In some embodiments, the discharging device 103 may perform one or moreoperations on the at least one analyte after it has been collected. Thedischarging device may include a Lab-on-a-chip (LOC) (a device thatintegrates laboratory functions on a single chip) for performing one ormore operations on the at least one analyte after it has been collected.The one or more operations may include, but are not limited to,analyzing the at least one analyte within the body, sorting the at leastone analyte, concentrating the at least one analyte, and diluting the atleast one analyte. For example, the discharging device 103 isillustrated with port 117 to blood vessel 118. For example, thedischarging device 103 may collect blood from blood vessel 118 via port117 and analyze the blood to determine a glucose level of the blood. Byway of another example, discharging device 103 may sort the blood toisolate a blood component from the blood, such as white blood cells,blood plasma, or blood serum. Discharging device 103 may include acentrifuge mechanism configured for sorting the blood. The centrifugemechanism may cause the blood to separate into the components of theblood based on differing densities. Denser components may separate fromless dense components spatially within the centrifuge mechanism. Thecentrifuge mechanism may include a plurality outlets interspersed atvarious points such that differing blood components may exit thecentrifuge mechanism via different outlets of the plurality of outletsbased on their differing densities. Alternatively, discharging device103 may include hydrophilic and hydrophobic regions. Blood may be passedthrough the hydrophilic and hydrophobic regions and hydrophilic portionsof the blood may collect in the hydrophilic region while hydrophobicportions of the blood may collect in the hydrophobic region. Lipids, ahydrophobic portion of the blood, may be separated from the blood bycollecting the portions of the blood that have collected in thehydrophobic region. Alternatively, discharging device 103 may include asurface capable of binding antibodies. The blood may be passed over thesurface, binding antibodies from the blood. The blood, less theantibodies that have bound to the surface, may be removed. Then, thesurface may release the antibodies, allowing the antibodies to becollected. By way of a further example, discharging device 103 mayconcentrate the blood by removing water from the blood, for example, byfiltration. By way of yet another example, discharging device 103 maydilute the blood by adding water to the blood. It should be understoodthat the above examples are merely exemplary and it is contemplated thatthe discharging device 103 may perform other operations on blood or onone or more analytes other than blood. By way of still another example,referring to FIG. 1 b, sampling device 120 is illustrated with shunt 124to lymph node 125. Sampling device 120 may collect material from lymphnode 125 via shunt 124 and may analyze the material, sort the material,concentrate the material, or dilute the material.

Referring again to FIGS. 1 a through 1 c, in exemplary embodiments, thedischarging device 103 may eject the collected at least one analyte fromthe body 101 through at least one dermal layer 102 of the body 101 viaejector 107. Ejector 107 may comprise a microjet. A microjet utilizespressure to force or displace material through an extremely smalldiameter opening, i.e., a micro-nozzle (for example, approximately50-200 μm), enabling the material to penetrate at least one dermal layerof a body without substantially damaging the dermal layer. For example,ejector 107 may utilize pressure to force or displace the at least oneanalyte through micro-nozzle 119 enabling the at least one analyte topenetrate at least one dermal layer of a body without substantiallydamaging the dermal layer. In this example, micro-nozzle 119 may beapproximately cylindrical in shape and have a diameter of approximately50-150 μm. By way of another example, ejector 107 may comprise a MEMS(microelectromechanical systems) based microjet formed by apiezoelectric transducer bonded to a silicon wafer with a micro-nozzlewhich forces or displaces the at least one analyte through themicro-nozzle enabling the at least one analyte to penetrate at least onedermal layer of a body without substantially damaging the dermal layer.Ejector 107 may comprise a liquid microjet that utilizes pressure toforce or displace a small volume of liquid through a micro-nozzleenabling the liquid to penetrate at least one dermal layer of a bodywithout substantially damaging the dermal layer. For example, ejector107 may utilize pressure to force or displace the at least one analyteas a liquid through micro-nozzle 119 enabling the material to penetrateat least one dermal layer of a body without substantially damaging thedermal layer. In this example, micro-nozzle 119 may be cylindrical inshape and have a diameter of approximately 50-100 μm. By way of anotherexample, ejector 107 may comprise a MEMS-based liquid microjet formed bya piezoelectric transducer bonded to a silicon wafer with a micro-nozzlewhich forces or displaces the at least one analyte as a liquid throughthe micro-nozzle enabling the at least one analyte to penetrate at leastone dermal layer of a body without substantially damaging the dermallayer. Ejector 107 may comprise a pulsed liquid microjet that utilizespressure to force pulse of liquid through a nozzle enabling the pulse ofliquid to penetrate at least one dermal layer of a body withoutsubstantially damaging the dermal layer. For example, ejector 107 mayutilize pulses of pressure to force or displace liquid throughmicro-nozzle 119 at a frequency of approximately 1 Hz to 10 Hz enablingthe material to penetrate at least one dermal layer of a body withoutsubstantially damaging the dermal layer. By way of another example,ejector 107 may comprise a MEMS-based liquid microjet formed by apiezoelectric transducer bonded to a silicon wafer with a micro-nozzlewhich utilizes pulses of pressure at a frequency of approximately 1 Hzto 10 Hz to force or displace the at least one analyte as a liquidthrough the micro-nozzle enabling the at least one analyte to penetrateat least one dermal layer of a body without substantially damaging thedermal layer.

Alternatively, ejector 107 may include a needle. The needle may beconfigured to be controllably deployed and retracted. The needle may beconfigured such that the needle does not penetrate through the at leastone dermal layer 102 of the body 101 when retracted and does penetratethrough the at least one dermal layer 102 of the body 101 when deployed.For example, ejector 107 may be configured to controllably deploy theneedle to penetrate through the at least one dermal layer 102 of thebody 101, eject the collected at least one analyte from the body 101through the at least one dermal layer 102 of the body 101 via theneedle, and then retract the needle.

In an embodiment, the discharging device 103 may eject the collected atleast one analyte from the body 101 through at least one dermal layer102 of the body 101 utilizing high pressure. High pressure may bepressure sufficient to eject at least one analyte from the body 101through at least one dermal layer 102 of the body 101 withoutsubstantial damage to the at least one dermal layer 102 of the body 101.For example, the discharging device 103 may eject the collected at leastone analyte from the body 101 through at least one dermal layer 102 ofthe body 101 at a velocity of at least approximately 100 m/s. Ejector107 may include a pressure generating mechanism for generating pressureincluding, but not limited to, a spring-loaded pressure generatingmechanism or a piezoelectric pressure generating mechanism. For example,ejector 107 may comprise an electrically powered piezoelectric actuatorwhich displaces a plunger in an acrylic micro-nozzle to eject the atleast one analyte from the body 101 through at least one dermal layer102 of the body 101. In this example, the volume and velocity of theejected at least one analyte may be controlled by controlling thevoltage and rise time of the electrically powered piezoelectricactuator. By way of another example, ejector 107 may comprise a loadedspring which displaces a plunger in a micro-nozzle to eject the at leastone analyte from the body 101 through at least one dermal layer 102 ofthe body 101. By way of still another example, ejector 107 may comprisea MEMS-based microjet formed by a piezoelectric transducer bonded to asilicon wafer with a micro-nozzle approximately 5-10 μm in diameterwhere a continuous pressure wave generated by the piezoelectrictransducer propagates the at least one analyte toward the micro-nozzleto eject the at least one analyte from the body 101 through at least onedermal layer 102 of the body 101.

In an embodiment, the at least one dermal layer 102 of the body 101 maybe subjected to an energy field to aid in the ejection of at least oneanalyte from the body 101 through the at least one dermal layer 102.Subjecting the at least one dermal layer 102 of the body 101 to theenergy field may create one or more pores in the at least one dermallayer 102 or may increase the permeability of the at least one dermallayer 102, aiding in the ejection of at least one analyte from the body101 through the at least one dermal layer 102. The energy field mayinclude, but is not limited to, an electrical energy field or anultrasonic energy field. The discharging device 103 or the receivingdevice 104 may include an energy field subjecting mechanism forsubjecting the at least one dermal layer 102 to the energy field.

For example, the collectedsignal may include that red blood cells have been collected. By way ofanother example, the collected signal may include that 10 μL of plasmais available to be ejected. The discharging transmitter 110 may transmita location signal enabling the discharging device 103 to be located. Thedischarging transmitter 110 may transmit a finished signal when thedischarging device 103 has finished ejecting the collected at least oneanalyte from the body 101 through at least one dermal layer 102 of thebody 101. The discharging transmitter 110 may transmit signals viaelectrical current, an electrical field, a magnetic flux, an opticalsignal, a radio frequency identification, an ultrasound, a vibration, anelectromagnetic signal, a force, a pressure, or any desired signaltransmission medium.

In another embodiment, the receiving device 104 may be aligned with thedischarging device 103 in preparation for ejection. The receiving device104 may be aligned with discharging device 103 utilizing a motorizedtrack system 116. Alternatively, receiving device 104 may be alignedwith discharging device 103 manually. The receiving device 104 mayinclude a signal receiver 113. The signal receiver 113 may receive alocation signal transmitted by discharging device 103 to guide alignmentof receiving device 104 with discharging device 103. Alternatively, thebody 101 may include a fiducial 130 to guide alignment of receivingdevice 104 with discharging device 103. The fiducial 130 may be locatedin proximity to discharging device 103. Alternatively, the fiducial 130may be located within discharging device 103. The fiducial 130 maycomprise any location marker including, but not limited to, afluorescent marker, a marker having an enhanced radio signature, a radiofrequency identification tag, a radio opaque marker, a retro reflector,a magnetic signature, a conductivity signature, or an ultrasonic marker.The fiducial 130 may also comprise a tattoo on the at least one dermallayer 102 of the body 101.
